BOSTON -- Manager John Farrell and the Red Sox won't always have the luxury of being able to use the best starting pitching depth option.

A sudden injury to someone in Boston's rotation could result in the most rested depth starter at Pawtucket receiving the start for Boston, not the most preferred option.

But who does Farrell think is the best option right now with everyone rested?

"With the benefit of having a couple of days notice, Kyle Kendrick certainly would be the guy that we would go to," Farrell said. "Beyond that, when you get into it three or four weeks, rest is going to be a key component to factoring in who's available. But coming out of spring training, Kendrick, (Henry) Owens, (Brian) Johnson, probably in that order."

Kendrick is the top option despite not being on the 40-man roster right now. He posted a 4-0 record and 2.18 ERA in eight outings (seven starts), 33 innings this spring.

The Red Sox had 10 different pitchers make at least one start last year.

Roenis Elias is on the disabled list now with a right intercostal muscle strain.

Owens and Johnson both struggled in camp.

Owens, who has dealt with serious control issues, went 0-3 with a 15.95 ERA in four outings (three starts). He allowed 13 runs, all earned, on 13 hits (two homers) and 12 walks while striking out 13 in 7 1/3 innings.

Johnson, who missed time last year being treated for anxiety and depression, went 0-2 with a 5.40 ERA in three outings (one start). He allowed seven runs, four earned, on 11 hits (one homer) and six walks while striking out five.
